|The Yashica looks like a Yashinon-DS from about 1975
Its certainly an M42, but like many later M42 lenses, it has no A/M switch. I think that it may be very similar (almost the same design, and even the same maker, the Tomioka factory) as the Mamiya SX 55/1.8. It may even be the same as the earlier Yashinon-DX and all the many similar lenses that came from Tomioka for Ricoh, Chinon, etc. Bill (member casualcollector) had a nice investigation of that.
I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work.
